Embodiment Construction

[0015] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0016] A preparation method of a medicinal hemostatic film material: the polyvinyl alcohol PVA material is prepared into a solution by a heating reflux method, and the solution is coated with a film applicator, dried in the air, and formed into a film. Measure the drying time, hardness, air permeability, water absorption, solubility and film-forming property of the material, and score them respectively.

[0017] The PVA is a mixture of PVA0588 and PVA1099 in a weight ratio of 2:2.

[0018] After the PVA is proportioned, water, glycerin, ethanol and sodium carboxymethylcellulose are added, and different solutions are prepared under the condition of heating to reflux. Make a film and let it dry.

[0019] Described water is 60ml, and glycerin...

Abstract

The invention relates to a preparation method of a medicinal hemostatic film material. The polyvinyl alcohol PVA material is prepared into a solution through a heating reflux method, and the solution is coated with a coating applicator, dried and formed into a film. The raw materials of the present invention are common and easy to obtain, and are powders, which are easy to process, so the cost is low, convenient to take and easy to popularize. Among the components of the invention, except yeast extract and pectin, the rest are people's daily food, so there is no side effect, and it is suitable for patients to take regularly.

Description

technical field [0001] The invention belongs to the technical field of hemostatic agents, and in particular relates to a preparation method of a medicinal hemostatic film material. Background technique [0002] Injuries are unavoidable in daily life, so local hemostatic materials are very important. Such as the first aid treatment of frequent sudden accidents, the hospital's wound hemostasis of patients is often used, especially the rescue of war wounded. [0003] Existing hemostatic gauze, hemostatic materials such as hemostatic fiber and hemostatic bandage all have certain limitations in use: easy to stick to the wound and not easy to change the dressing, also powerless to infection and suppurative wound. In order to reduce unnecessary deaths caused by blood loss, the medical community of various countries has higher requirements on the hemostatic performance of hemostatic materials, and it is imperative to develop materials with better hemostatic effects. Materials for ...
